I must admit I was also quite disappointed by the AS. There is no denying that it is an absolutely stunning lounge from a design and architecture point of view, and it is nice to have the sleeping rooms when available. However, I just didn't think it was comfortable, it was awkwardly quiet and I found the food to be meh.
Admittedly, there are few first class lounges to compare to the likes of the CX lounges in HKG, but I just didn't enjoy the AS.
On reflection, the fact that it was Ramadan and there was not alcohol may have affected my perception of the lounge.....
